Question: A certain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino. The parent nucleus was at rest at the origin of an xy coordinate system. The electron moves away from the origin with linear momentum (-1.2 x 10-22 kg · m/s) i; the neutrino moves away from the origin with linear momentum (-6.4 x 10-23 kg · m/s) j. What are the
(a) Magnitude and
(b) Direction of the linear momentum of the daughter nucleus?
(c) If the daughter nucleus has a mass of 5.8 x 10-26 kg, what is its kinetic energy?
